My '09 has the 4.6 in it and I've noticed that latley it's running pretty cold. Even with 100+ degree temps it's staying almost all the way cold on my drive home from work and doesn't start to rise until I'm about home.

I did a search but couldn't come up with anything. Any idea's?

Thanks.

 

gotta be the gauge, sensor in the coolant or the thermostat is stuck open.

 

I would say thermostat is bad. Put a new one on it and see what happens.

 

I only have about 38,000 on it. I'm hoping it's only the thermostat
